At Metalsin, we specialize in manufacturing EN 1171-compliant ductile iron gate valves designed for demanding water supply and wastewater treatment systems. Our resilient seated, non-rising stem gate valves are engineered for reliability and longevity, featuring flanged ends meticulously aligned with EN 1092-2 drilling dimensions. This adherence ensures seamless compatibility with pipelines and fittings in water infrastructure projects designed to European standards. …

At Metalsin, we specialize in manufacturing water supply gate valves that meet the rigorous demands of EN 1074-1, EN 1074-2. They are usually ductile iron gate valves manufactured in accordance with EN 1171. These gate valves, either used above or below ground, are engineered for reliability in potable water systems, industrial pipelines, and municipal infrastructure. Available in resilient-seated (soft sealing) or metal-seated (hard sealing) configurations, these valves …

Metalsin supplies motorized wafer butterfly valves with electric actuators to water supply and water treatment pipelines. They are also known as electric actuated wafer butterfly valves. The term “motorized” refers to that the valve is operated by an electric actuator, which serves as the driving force by converting electrical energy into mechanical motion to rotate the valve disc. It typically …

Metalsin supplies versatile pneumatic-actuated lug butterfly valves for waterworks applications. These valves feature the pneumatic-actuated operation method: The butterfly valve is driven by a pneumatic actuator, which is a device that uses compressed air to automate the operation of the valve, enabling it to open, close, or modulate flow. Pneumatic actuators are widely used in waterworks applications due to their …

Design Features Metalsin supplies EN 593 double eccentric butterfly valves to waterworks applications, which are gear operated with double flanged ends. These valves feature: Double eccentric design: This design is also known as double offset. The first offset is an axial offset of the shaft to the seating contact. The second offset is an offset from the valve body (or …

Design Features Metalsin supplies EN 593 concentric flanged butterfly valves, which are worm gear operated and furnished with a pinless shaft. They have the following design characteristics: Concentric design: It features the valve disc and shaft (stem) that share the same centerline within the valve body, ensuring simple construction and efficient operation. This design is commonly used for low-pressure applications, …

Metalsin supplies double-shaft wafer type butterfly valves manufactured in accordance with EN 593. These valves are widely used in water treatment plants and water supply and distribution lines. Double Shaft vs. One-Piece Through Shaft The shaft of a butterfly valve, also known as “stem”, is a bar extending through the body hubs and into the disc to support the disc …

Design Features Metalsin supplies EN 593 lug type butterfly valves for waterworks projects. The lug butterfly valve is clamped between two pipe flanges of adjacent components when installed. The lug-style body has one integral flange with an identical hole pattern to the piping flanges. The bolt hole on each lug may be either threaded hole or drilled hole. A drilled …

Design Features Metalsin supplies EN 593 wafer type butterfly valves for waterworks engineering. These valves have the following design features: Designed to EN 593: It is the European standard that specifies the requirements for metallic butterfly valves for general purposes. Wafer type body: Also known as flangeless body, it is a flat body that has a minimal face-to-face, which is …

Design Features Metalsin supplies AWWA C504 flanged double eccentric butterfly valves to various waterworks pipelines. The double eccentric butterfly valve, also known as a double offset butterfly valve, features a design where the valve stem is offset from both the centerline of the disc and the centerline of the valve body. The first eccentricity is the offset between the valve …

Metalsin supplies the waterworks project with AWWA C504 flanged concentric butterfly valves which are rubber seated. It features a design where the valve stem axis is perfectly aligned with the centerline of both the butterfly disc and the valve body. This concentric alignment ensures that the disc remains in constant contact with the soft sealing seat (typically made of materials …

The AWWA C504 rubber seated butterfly valve is a valve that uses a disc rotatable through an angle of approximately 90° as a closure member. The valve is closed when the edge of the disc is perpendicular to the flow way, open when parallel to the flow way, or used for throttling when positioned between open and closed. It has …
